Definitions

  • the invention relates to a method for treating a fiber cable for the production of synthetic staple fibers according to the preamble of claim 1 and an apparatus for carrying out the method according to the preamble of claim 9.
  • the fiber cable formed from a plurality of synthetic filament strands is first passed through a moistening device in the form of a dip bath to ensure uniform wetting of all fiber strands and thus secure cohesion of the individual fibers during the treatment to obtain.
  • a spin finish is preferably used which allows a safe running of the fiber cable over the treatment facilities of the fiber line.
  • the fluid within the fiber cable leads to a substantially good and uniform heat transfer and a mobility of the filament strands with one another during the drawing process. Only with a sufficient moisture content can the fiber cable be produced with high strands. Thus, the wet fiber tow is then stretched in a draw zone between two stretch rolling mills.
  • the stretched fiber cable is then guided over several heated calender rolls for fixing and drying.
  • the fiber cable is fed to a squeezing device immediately before entry into the fixing device, in which the fiber cable is passed through a nip formed by steel rollers. In this way, the fluid can be led out of the fiber cable in large quantities before the fiber cable is treated on the calender rollers becomes. After drying and fixing of the fiber cable cooling and crimping of the fibers takes place in order to then cut them into staple fibers.
  • a further object of the invention is to make a reduction of the fluid in the fiber cable such that a uniform width distribution of the residual fluid in the fiber cable prevails.
  • the invention takes a completely new approach, which was previously regarded in the art as not feasible because the prevailing opinion was that a squeezing of the fiber cable would lead to a high degree within a draw zone to damage the fibers.
  • a squeezing of the fiber cable would lead to a high degree within a draw zone to damage the fibers.
  • a high degree of fluid from the fiber cable could be removed already within the draw zone.
  • the squeezing of the fiber cable within the draw zone was carried out over the entire width of the fiber cable such that sets over the treatment width of the fiber cable, a uniformly distributed weight fraction of ⁇ 10% of the fluid in the fiber cable.
  • the device according to the invention has bending-resistant squeezing means which squeeze the fiber cable uniformly over the entire width and at substantially predefined pressure for squeezing out the fluid.
  • the actual stretching process of the fiber cable remains unaffected thereby, so that the liquid content required for the stretching in the fiber cable can have a correspondingly high proportion by weight in the range of> 20%.
  • a particular advantage of the invention is that the fiber cable can be fed to the squeezing device in a region with relatively low running speeds. In that regard, vibrations and irregularities can be avoided.
  • a secure guidance of the fiber strands is ensured by the squeezing agent without any entrainment of individual fibers.
  • the low speeds also increase the exposure time when squeezing the fiber cable, so that the fluid can be led out of the fiber cable in large quantities.
  • the development of the invention is preferably used in which the fiber tow is squeezed in the lead-in area of a drafting mill bounding the draft zone, wherein the fiber tow is heated within the draw zone by a heated fluid to a draw temperature to induce a draw point in the fibrous material.
  • the fiber cable is preferably passed through a steaming channel with hot steam or through a temperature-controlled drawing bath.
  • the squeezing device is arranged in the inlet of the second drafting roller mill, so that the filament strands entering the squeezing device already have their essential stretching.
  • the fiber cable has proven particularly useful when the squeeze means are formed by steel rollers having a nip between them.
  • the steel rollers are held against each other with a line load in the range of 30 N / mm to 100 N / mm. This ensures that even with large quantities of liquid within the fiber cable, a weight fraction of ⁇ 10% fluid is established.
  • the fiber cable in the nip is compressed to at least 70% of its original cable thickness. This makes it possible, in particular for the drawing process, to have a high fluid content, which may be in the region of above 40%.
  • the fiber cable is squeezed during emergence on a first draw roll of the second draw roll mill by a voltage applied to the draw roll pressure roller.
  • the predetermined for stretching threadline of the fiber cable can be maintained.
  • the facilities of the squeezer are reduced to a minimum, since a separate drive for driving the steel rollers is not required. Due to the driven draw roller, the pressure roller can advantageously be driven solely by friction.
  • the development of the method according to the invention is preferably used, in which the fiber tow are heated by the heated draw rolls of the second draw roll mill after the squeezing of the fluid. Due to the low fluid content in the fiber tow, the energy provided by the draw rolls can be used directly to heat the fiber tow. Loss energy that would only be used to heat a fluid is kept to a minimum.
  • the fiber tow is guided after stretching over several calender rolls, whereby the energy required for drying the fiber tow can also be reduced to a minimum due to the low fluid content of the fiber tow.
  • the inventive method represents a particularly advantageous and safe treatment option of a fiber cable, in which compared to conventional methods considerable energy savings can be realized. For example, by squeezing the fiber cable, the energy for fixing the fiber cable can be reduced by 20% even before it enters the second drafting roller mill. Another particularly advantageous effect arises during the heat treatment for fixing the fiber cable. Due to the low fluid content in the fiber cable, higher fiber strengths are achieved. ranges, which could be increased by 6 to 10% compared to conventional methods.

  • the pressure roll is preferably formed with a deflection-compensated steel shell, so that the nip between the pressure roll and the draw roll over the entire width of the fiber cable is the same size.
  • the deflection-compensated steel shell of the pressure roller is designed such that the nip is present with a gap width variance of ⁇ 0.05 mm. This can be realized over the width of the fiber cable very uniform fluid fractions.
  • the squeezing force required between the steel rollers for compressing the fiber cable is advantageously generated by an energy generating device which generates at least one roll over the width of the steel uniform line load in the range of 30 N / mm to 100 N / mm.
  • the device according to the invention can be designed in such a way that several roller pairs are provided in several successive positions.
